-Subject: [PATCH 118/182] ata: ahci_platform: runtime resume the device before
- use
-
-On OMAP platforms the device needs to be runtime resumed before it can
-be accessed. The OMAP HWMOD framework takes care of enabling the
-module and its resources based on the device's runtime PM state.
-
-In this patch we runtime resume during .probe() and runtime suspend
-after .remove().
-
-We also update the runtime PM state during .resume().
